Original Sound Quality
{{unreferenced, date=March 2010 Original Sound Quality (OSQ) is an audio file format developed in 2002 by '' Steinberg Media Technologies GmbH'' and implemented e.g. in their audio editing software ''Wavelab 4'' (and following releases) for lossless audio data compression. In combination with good source material this format allows compression rates up to 50%. Because of that it is not comparable to other audio formats like MP3, which reach compression rates up to 90% because of their lossy compression In information technology, lossy compression or irreversible compression is the class of data compression methods that uses inexact approximations and partial data discarding to represent the content. These techniques are used to reduce data size ... algorithms. Therefore, OSQ is used rather for archiving then for daily use. When using this format it is important to know that OSQ is a proprietary format developed by ''Steinberg'' that is generally speaking not supported by othe ...

Audio File Format
An audio file format is a file format for storing digital audio data on a computer system. The bit layout of the audio data (excluding metadata) is called the audio coding format and can be uncompressed, or compressed to reduce the file size, often using lossy compression. The data can be a raw bitstream in an audio coding format, but it is usually embedded in a container format or an audio data format with defined storage layer. Format types It is important to distinguish between the audio coding format, the container containing the raw audio data, and an audio codec. A codec performs the encoding and decoding of the raw audio data while this encoded data is (usually) stored in a container file. Although most audio file formats support only one type of audio coding data (created with an audio coder), a multimedia container format (as Matroska or AVI) may support multiple types of audio and video data. There are three major groups of audio file formats: * Uncompressed audi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Steinberg
Steinberg Media Technologies GmbH (trading as Steinberg) is a German musical software and hardware company based in Hamburg. It develops music writing, recording, arranging, and editing software, most notably Cubase, Nuendo, and Dorico. It also designs audio and MIDI hardware interfaces, controllers, and iOS/ Android music apps including Cubasis. Steinberg created several industry standard music technologies including the Virtual Studio Technology (VST) format for plug-ins and the ASIO (Audio Stream Input/Output) protocol. Steinberg has been a wholly owned subsidiary of Yamaha since 2005. History The company was founded in 1984 by Karl Steinberg and Manfred Rürup in Hamburg. As early proponents and fans of the MIDI protocol, the two developed Pro 16, a MIDI sequencing application for the Commodore 64 and soon afterwards, Pro 24 for the Atari ST platform. The ST had built-in MIDI ports which helped to quickly increase interest in the new technology across the music world. In ...

Wavelab
WaveLab is a digital audio editor and recording computer software application for Windows and macOS, created by Steinberg. WaveLab was started in 1995 and it is mainly the work of one programmer, Philippe Goutier. Audio can be edited as a single file, a series of files or a multitrack "montage". It fully supports VST 2 and 3 plugins for audio processing. Cut-down versions of WaveLab are available as WaveLab Elements and WaveLab LE. Features and usage In addition to recording audio from multiple sources, WaveLab can be used for post-processing of all types of audio. It is popularly used for mastering audio, but also facilitates basic usage such as editing podcasts. * Single-window dockable user interface with multiple themes, fully scalable * Maximum sample rate of 384 kHz and bit rate of 32-bit floating point * Encodes, imports and allows editing metadata of various file formats such as WAV, FLAC, OGG, AIFF, MP3 and AAC * DDP (Disc Description Protocol) and included sh ...

Data Compression
In information theory, data compression, source coding, or bit-rate reduction is the process of encoding information using fewer bits than the original representation. Any particular compression is either lossy or lossless. Lossless compression reduces bits by identifying and eliminating statistical redundancy. No information is lost in lossless compression. Lossy compression reduces bits by removing unnecessary or less important information. Typically, a device that performs data compression is referred to as an encoder, and one that performs the reversal of the process (decompression) as a decoder. The process of reducing the size of a data file is often referred to as data compression. In the context of data transmission, it is called source coding; encoding done at the source of the data before it is stored or transmitted. Source coding should not be confused with channel coding, for error detection and correction or line coding, the means for mapping data onto a signal. ...

Lossy Compression
In information technology, lossy compression or irreversible compression is the class of data compression methods that uses inexact approximations and partial data discarding to represent the content. These techniques are used to reduce data size for storing, handling, and transmitting content. The different versions of the photo of the cat on this page show how higher degrees of approximation create coarser images as more details are removed. This is opposed to lossless data compression (reversible data compression) which does not degrade the data. The amount of data reduction possible using lossy compression is much higher than using lossless techniques. Well-designed lossy compression technology often reduces file sizes significantly before degradation is noticed by the end-user. Even when noticeable by the user, further data reduction may be desirable (e.g., for real-time communication or to reduce transmission times or storage needs). The most widely used lossy compression al ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Proprietary Format
A proprietary file format is a file format of a company, organization, or individual that contains data that is ordered and stored according to a particular encoding-scheme, designed by the company or organization to be secret, such that the decoding and interpretation of this stored data is easily accomplished only with particular software or hardware that the company itself has developed. The specification of the data encoding format is not released, or underlies non-disclosure agreements. A proprietary format can also be a file format whose encoding is in fact published, but is restricted through licences such that only the company itself or licensees may use it. In contrast, an open format is a file format that is published and free to be used by everybody. Proprietary formats are typically controlled by a company or organization for its own benefits, and the restriction of its use by others is ensured through patents or as trade secrets. It is thus intended to give the licence ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Free Lossless Audio Codec
FLAC (; Free Lossless Audio Codec) is an audio coding format for lossless compression of digital audio, developed by the Xiph.Org Foundation, and is also the name of the free software project producing the FLAC tools, the reference software package that includes a codec implementation. Digital audio compressed by FLAC's algorithm can typically be reduced to between 50 and 70 percent of its original size and decompresses to an identical copy of the original audio data. FLAC is an open format with royalty-free licensing and a reference implementation which is free software. FLAC has support for metadata tagging, album cover art, and fast seeking. History Development was started in 2000 by Josh Coalson. The bit-stream format was frozen when FLAC entered beta stage with the release of version 0.5 of the reference implementation on 15 January 2001. Version 1.0 was released on 20 July 2001. On 29 January 2003, the Xiph.Org Foundation and the FLAC project announced the incor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Computer File Formats
A computer is a machine that can be programmed to carry out sequences of arithmetic or logical operations (computation) automatically. Modern digital electronic computers can perform generic sets of operations known as programs. These programs enable computers to perform a wide range of tasks. A computer system is a nominally complete computer that includes the hardware, operating system (main software), and peripheral equipment needed and used for full operation. This term may also refer to a group of computers that are linked and function together, such as a computer network or computer cluster. A broad range of industrial and consumer products use computers as control systems. Simple special-purpose devices like microwave ovens and remote controls are included, as are factory devices like industrial robots and computer-aided design, as well as general-purpose devices like personal computers and mobile devices like smartphones. Computers power the Internet, which links bil ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lossless Audio Codecs
Lossless compression is a class of data compression that allows the original data to be perfectly reconstructed from the compressed data with no loss of information. Lossless compression is possible because most real-world data exhibits statistical redundancy. By contrast, lossy compression permits reconstruction only of an approximation of the original data, though usually with greatly improved compression rates (and therefore reduced media sizes). By operation of the pigeonhole principle, no lossless compression algorithm can efficiently compress all possible data. For this reason, many different algorithms exist that are designed either with a specific type of input data in mind or with specific assumptions about what kinds of redundancy the uncompressed data are likely to contain. Therefore, compression ratios tend to be stronger on human- and machine-readable documents and code in comparison to entropic binary data (random bytes). Lossless data compression is used in many ...
